I'm fairly certain Google Maps also lists busy times for specific locations, at least it does for restaurants and stores.
This is all very on-brand from Florida, a place where according to Republican logic, this is not supposed to happen because open carry should've brought all those supposed "good guys with a gun" out of the woodwork. Gee, I can't possibly imagine why more guns isn't making us safer. /s
There is no concealed carry allowance/license in any State that I'm aware of that makes it legal to carry everywhere. Surely you've seen those "No Guns Allowed" window stickers at businesses and public buildings. Most States prohibit concealed carry anywhere that sells alcohol, so a lot of restaurants are off limits. Fact is, most places where these mass shootings occur are "gun free" zones either by statute or private property preference.
The idea that "carry" laws mean that people can be armed everywhere and therefore are a one-stop solution for mass shootings is ridiculous. One cannot use "carry" law's existence as either a gotcha for "concealed carry laws don't work," nor for "more gun restrictions are good," because neither is accurate.
